ROOF BINDING.

Application filed December 30, 1925. Serial No. 78,402.

My present invention has reference to a simple means for protecting the ends and edges of composition roofings as well as to afford a better watertight joint between the roofing and the sheathing of'a building.

To the attainment of the foregoing the invention consists in the improvement as hereinafter described and definitely claimed.

In the drawings Figure 1 is a top plan view lllustrating the application of the improvement, parts being broken away and parts-being in section.

Figure 2 is a section on the line 2-2 of Figure 1. s

Figure 3 Figure 1.

Figure 4 is a perspective view of one of the edge strips.

Figure 5 is a similar view of one of the end strips.

The sheathing ofa building, in Figure 1 of the drawings, is indicated by the numeral 1. This building is covered by a composition roofing 2. 7

As is well known in the art, composition roofings break or crack when attached to the ends and edges of a roof structure and thereafter soon decay and rot, so that a water tight roof is hard to obtain.

In carrying out my invention I make use of metal members which engage the ends and the edges of the'roofing 2 ma manner to. permit of the said ends and edges being effectively secured on thereof or sheathing and likewise aflord a water tight joint between the roofing and thereof.

InFigure 5 of the drawings I have illustrated the metal member which is arranged on what I have termed the ends of the roofing 2. These metal members are arranged in strips which are centrally bent upon themselves to provide flanges 3 and 4, disposed one over the other but which, before being applied, have their free edges spread away from each other. The cross sectional U.- shaped strips thus provided receivethe ends. of the roofing 2 therein, while securing means, such as the ordinary nails 5 are passed through the U-shaped strips and the roofing and, of course, enter the roof.

is a section on the line 3-3 of prising a metal plate,

provide an inwar The protective means for the edge of the roofing is illustrated in Figure 4 of the drawings. This means is also in the nature of a metal member bent upon itself to provide a lower flange 6 and an upper flange 7. The upper flange is-of a greater length than the lower flange and has its outer end rounded downwardly and inwardly to provide a small bead 8. The edge of the roofing is passed over the upper flange 7, around the bead 8 and between t e flanges 7 and 6. The ends of the metal device above described, and which is broadly indicated by the numeral 9. are received between the flanges 3 and 4 of the metal strips which are broadly indicated by the numerals 10 and the nails 5 that pass through the outer ends of the said members 10 also pass through the member 9.

From the foregoin description, when read in connection wit the accompanying drawings, it will be notedthat I have produced a simple and effective means for protecting the ends and edges of complosition roofs and for establishing a water ti t joint between the roofing and the roof. fln addition to this it will e noted that the elements 9 have their beaded edges projecting beyond the roof so as to afford an effective water-shed for the roof. Of'course, other securing means may pass through the elements 9, but as such elements are forced through two layers'of roofing 2, that is, the

entrance of water through the openin s made by the said nails will be effective y prevented.

Having described the invention, I claim An edging for composition roofings, com- "provide an underlying and an overlying flange, the overlymg flange" being of a greater width than the underlying flange,

and the outer edge thereofbeing rolled to ly directed bead which is spaced from the outer edge of the underlying flange a of the roofing between said flanges.

In testimony whereof I aflix my signature.
